This invention relates to button loops of the type having dependingresilient arms the terminals of which are tormed for a relative movableassociation ith-an attached member providing a seatforthe shank of abutton Within the loop.

' The objects of the invention are to 7 provide a two-part expansiblebuttonloop of.

which a contracted P01110110}? one part is inexpansibly held by an axialstrain upon the other part; to provide a t vospart button loop of whichone part is of rigid structure and the other part is laterally,exp'a-nsibleonly upon the relative axially yielding movement of therigid part and to provide ithWO-Pftlll. button loop with integralconnections adaptingthe forcedmovement of one part to con-' sequentiallyproduce a movement of: the other part in the plane of the"loop,butatright angles to the forced movement; fWith these and other objectsin'view the inventionconsists inthe novel constructions, to be hereinafterdescribed or-claimed', forcarrying' out understood byreference tooneillustrative de the above stated objects and'such other objects ashereinafter may. be made to appear.

The character of the inventionmaybe best vice embodying the novelfeatures herein disclosed and illustrated by the accompanyingdrawings-1n Which the Figure 11s an elevation of the contracted loop;the F1gure'2 is an elevati on of the expanded loop and the Figure 31s aplan View ,oi 'a rig d part, the Figures i and 5 being modifiedstructures. I

The device, as illustrated, comprises; the suspension loop 1, thebutton+receiving loop 2, the normally contracted throat portion *3,"

and the button-retaining loop 4:, the said loops 1, 2, and 4. beingaxially associated in that an imaginary vertical center hne of one loopis he center line of each of the other loops. The

device ismade in two parts one of Which is I of resilient Wire of whicha middle portion is bent to form the suspension loop 1, the other Wire.portlons depending therefrom .to provide the spring side arms 5 and6'cooperating to provide the button-receiving loop 2 and the normallycontracted throat portion 3,'the

Wire adjacent both ends being bent relatively divergent to provide thedivergent guides .7

dition will be maintained by the relatively oorrrmor our, A oonronarronor 0on5 Borrow-Loo? 1 andi8", illustrated bythe Fig ur 1 and a purposeto be explained. Stops 9 and 10 integral sleeves 12 and 13 formed upthereon "for a sliding mounted engagement upon the I uides 7 and 8,respectively, the lugs l ibeing integrallyprovided by the sleeves 12 and'13 8 in bothlongitudinal directions to maintain the rigid loopstructure11 in theplane of the button loop' as illustrated by the'Figures 1 and 2Informing the sleeves 12 and 13 the diameters of each are made to lie inthe plane ofthe flat rigid loop structure 11, andhence in thep-lane ofthe button loop, so that the complete devicemay be reversible in thesense that an elevation reverse to that illustrated .bythe, Figure lWlllbe identical therewith.

When the shank S of a button rests vWithin the retaining loop 4 and apulling; stress of the button loop against the rigid loop structurell,as illustrated by the Figure 1.,

the sleeves 12 and 13 are necessarily madeto e5 assume positions uponthe guides 7 and 8 close to the stops '9 and 10, thereby contract} ingthe arms 5 and 6, andrhenc'e the throat portion 3, this contractedcondition {being maintainable regardless of the spring tension of thearms 5 and 6 so long as the pulling arms 5 and 6 become insuflicient tonormally maintain a, closed throat portion 3, that conlow position ofthe rigid loop structure 11' upon'the guides7 and 8. Upon .the passing.ofthe shank S through the throat portion 3 thethroat is thereby;expanded laterally as illustrated by the Figure, 2. In order how- 5 sois placed upon the shanlr, and hence axially on stress is exerted uponthe rigid loop structure 11. 7 Therefore, should the tension of the everthat the throat 3 be permitted to so expand the rigid loop structure 11must bodily yield axially of the button loop upwardly toward the throatfor, as the distance between the guides 7 and 8 increases upon theexpansion of the throat portion 3,the sleeves 12 and 13 being ofrelatively fixed dependence must ver associate themselves withcorrespondingly spaced portions of the divergent guides 7 and 8 uponwhich they are mounted and therefore slide thereon to their upperpositions. Therefore, as the resilient member of the button loop expandslaterally, the rigid loop structure 11 must bodily yield axially oi thebutton loop in an upwardly direction and, as a pulling stress is placedaxially of the button. loop upon the rigid loop structure 1], and bearsthe structure 11 bodily downward, the arms 5 and 6, and hence the Vthroat portion 3, must as a matter of consequcnce contract laterally.

The Figure stillustrates a fragmentary part of a button 100 of identicalconstruction with that of the preferred form above explainedexceptingthat the guides 7 and 8 are provided with stops 8A and 9A of modiliedform. In place of looping the extremities of the guides 7 and 8 toprovide stops, the stop 8A and 9A are provided by upsetting each end ofthe guides. In this modified form the lower of the lugs 14 are omittedto permit the closer relation between the sleeves and the stops upon ther'gid loop sl'ructiu'e l1 assuming its lower position upon the guides 7and 8.

The Figure 5 illustrates a button loop of which the resilient part isidentical with that of the preferred form. T he rigidly constructed parthmvever modi'lied in that it is made of wire, Inthis modi lied form thewire provides a rigid bar 11A. having at either end fixed loops 12A and13A, each having a portion laterally oil-set, one toward the other, inorder that the loops 12A and 13A ma freely slide over their respectiveguides 7 and S as the rigid structure assun'ies its upper and lowerpositions already explained with regard to the preferred rigid loopstructure 11.

I claim:

1. A two-part expansible button loop providing axially assoc ated loops,one part comprising, in part, a resilient wire button receiving loophaving; a normally closed throat portion and Wire terminals depcndiinrtherefrom, and the other part comprising a rigid sheet metalbutton-receiving member, and connection integrally provided by each ofthe parts, the connections including a paPr of relatively divergentguides having stops and provided by the terminals of the resilient wirepart, and sleeves rigidly provided by the rigid member for slidingengagement upon the divergent guides for a yielding relative movement ofthe parts in an axial diassent rection of the associated loops thethroat portion is laterally expanded and con tracted.

2. An expansible button loop having axially associated resilient andrigid loop members, the resilient member providing the button loop withan intermediate laterally expansible throat portion normally contracted,and each member being so constructed and both members being so assembledone to the other that both members are thereby maintained in a commonplane anc as the throat portion is laterally expanded, the rigid memberthereby bodily moved to an axially upward position relative to theresilient nember and, as a downward axial stress placed upon said rigidmember the rig member is thereby bodily moved to a l'nver position,relative to the resilient memliier, such stress cooperatino wiih theresilient tension of the throat pelt-ion in maintaining a normallycontracted throat portion.

3. An expansible button loop h ving axially associated resilient andrigid loop members, the resilient member providing the button loop withan intermediate laterally '-r-:- pansible throat portion normallyclosed, and each member being so constructed and both members being so awembled one to the other that, both members are thereby maintained in acommon plane, and, s the throat portion is laterally expanded, the rigidmember is thereby bodily moved to an axially upward position relative tothe resilient niemb r and, as a downward axial stress is placed uponsaid rigid momh I the rigid member is thereby bodily moved to a lowerposition, relative to the resilient member, such stress cooperating withthe tension or" the res lient loop in maintaining a normally closrportion.

4. A twoart expansih e button loop pro viding axially ass'iciated loops,one part comprising, in part, a resilient wire buttonreceiving loophaving a normally closed throat portion and wire portions dependingtherefrom, and the other part comprising a rigid sheet metal bulidrnretaining loop member, and connections integrally provided by each ofthe parts, and adapted to maintain the parts in a common pl' ne,theconnections including a pair of platively diver-geld; ,QfllllClQShaving stops and provided by the depending wire portions of the re,liens wire part, and sleeves rigidly provided by the rigid member for siding on ement upon the divergent guides for a yielding relative bodilymovement of the parts toward and away from one another in ar-iialdirections of the associated loops as the throat portion is laterallyexpanded and contracted.
